warning LNK4042: The same object file was specified more than once

Background: Libjingle移稙到VS2010下编译。按照Scons给出的工程结构建立了5个lib工程，以及一个call工程。编译jingle时出现warning LNK4042。开始我不管，后来发现编译call出错，凡是在constants.h/constants.cc中定义的变量都不能用，会出现LNK2019 error(出现这个error说明在产生lib的工程中，有一些变量被声明，但没有被定义，也就是说有一些文件没有被编译。见博文：http://blog.sina.com.cn/s/blog_872c0f460100zlrn.html）。
解决：原文地址：Visual Studio 2010's strange “warning LNK4042”
change the value under C/C++ -> Output Files -> "Object File Name" to be the following:
$(IntDir)/%(RelativeDir)/
问题的原因是代码结构中出现了同名的文件，虽然在不同的文件夹，但VS2008以后的版本都默认忽略文件夹结构，也就是说所有的文件在编译时被认为是在一个文件夹里。而同名的文件自然会被忽略而不被编译。
最后用一句话总结：永远不要忽略任何Link的warning!
